AApplication August 2, 1955, SerialNo. 526,040 1 claim. (ci. 21e-s4) Thepresent invention relatesgenerally 'to'applicators and more particularlyto an applicator for annularV gummed reinforcements, rings or patchescommonly employed to reinforce the pages of loose leaf notebooks and thelike at the edges of the apertures punched therein to receive `theattachment rings of the notebook.

The primary object of this invntion Ais to vprovide a device to applygummedreinforcements to paper.

.Another object of this invention is to provide an applicator which willhold a supply of -gummed reinforcements stacked on a magazine element,in readiness for application.

Another object of this invention is to -pr'o"\'i' ;lean applicatorwherein the stacked 'reinforcements are 'held loosely in order toprevent adherence to each other.

Another object of this invention is to provide an 'applicator soconstructed as to prevent inadvertent removal of the stackedreinforcements.

Another object of this invention is to provide an applicator which inuse will not damage underlying 'surfaces such as a desk top, or papersthereon.

Another object of this invention is to provide an applicator whichsupplies suiiicient uniformly distributed pressure upon the peripheralportion of the gummed reinforcements to assure adherence of`sa-idreinforcements to the page of the notebook or other articlebeingfp'rocessed.

Another object of this invention is .to provide an applicator which isadapted for .fabrication from many di'erent materials, so that thechoice of material can lbe according to the dictates of availability andprice considerations, the exact sizes and proportions being matterseasily determined to suit particular conditions'and needs.

Another object of this invention is to provide an applicator which lispracticable 'and inexpensive to manufacture.

Finally, it is an object to provide an applicator of the aforementionedcharacter which is simple, safe and convenient to use and which willgive.generally eflicie'nt and durable service.

With these and other objects definitely in view, this inventionconsistsin the novelconstruction, combination and arrangement ofelements and portions, as will be hereinafter fully described in thespecification, particularly pointed out in the claims, and illustratedin the drawing which forms a material part of this disclosure, and inwhich:

-Figure l is longitudinally sectioned view of the applicator in extendedposition.

yFigure 2 is a longitudinally sectioned view similar to Figure l, 'butshowing the parts in fully closed position, as when under pressure.

Figure 3 is a fragmentary, enlarged view, largely in section showing thelower end portions of the applicator with a -plurality of annular gummedreinforcements positioned on the magazine element of the applicator, theparts being illustrated in the positions thereof assumed ICS V2 when thelowermost of said reinforcements is being applied.

Fgure 4 is a fragmentary, enlarged view of the upper Y -tical elementsand portions throughout the specication and throughout the views of thedrawing.

ln substantially all business there is at times Ya need for theapplication of annular gumme'd reinforcements to prevent the tearing ofpaper in which vholes are punched for the purpose of 'mounting Aa sheetor sheets of paper in a ring binder or the like. This necessitatesVseveral steps, the first of which-is a search forza container in 'whichthe gummed reinforcements are stored. Next,

the removal of a single reinforcement from the container, thenmoistening the paper or the gummed reinforcement in some manner, -then'applying the reinforcement 'to the paper. I

Any one of these steps may present difficulties which aretime-'consuming and, therefore, expensive.

The present invention provides a means to store, 4inoisten, and applythe gummed reinforcements with great rapidity, thereby at leastfacilitating 'the previously mentioned steps. Y

Referring now to the drawings there is Vshown a housing lil of generallyhollow cylindrical form having a head l2 of a larger diameter vthan andx'ed normal to the upper end of the housing i0. The head 12 presents ailat interior surface 'to which is attached a sponge 'rubber mois'teninghead 14, and an interior surface to which is iixed a guide member 16 ininternal coaxial relationship with the housing 10 and the head 12. TheVguide member, as illustrated, extends throughout approximately'onehalfthe length of the housing v10. The housing '10 is Veinlarged in diameterat the end opposed to the head 12 t-o constitute a pressure head-Zhavinga substantially hat face 1S. The pressure head 20 is also provided'with'a bore 22 of slightly larger diameter than the internal diameterof the housing V10. Adjacent the face 1S, the pressure head has aIbevelled portion `23. l

A magazine 24 is provided, this magazine being of -hollow cylindricalform and of an external diameter to Ya1- low -insertion thereof into thepreviously mentioned housing JLG. vThe magazine has sliding relationshipwith the previously mentioned guide member 16. A compression spring 26is mounted coaxially on the guide member .16 and compressed between theupper end of the magazlne andthe `inner face of the head -12 to biasthe` magazine outwardly or downwardly. The magazine Zlis maintainedagainst withdrawal Vfrom the housing it) 'by a key 28 and slot 30arrangement. The key 28 is a protrusion on the surface of the magazine,and of a shape and dimension to allow passagel thereof through the slot30 -in an annular bead or ring Y3:2 on the inside of the `housing 10adjacent the innervend of the bore 2v2. Themagazine 24 may be removedvfrom or inserted iin-to the housing l() by rotating the magazine 24until the key 2S is in alignment with the slot 3l, and moving themagazine 24 axially in relationship with the housing 10. Afterinsertion, the magazine 2i) is rotated so that the key 28 is no longerin alignment with the slot 39. kSince substantially no rotationalmovement of the magazine 24 is caused by operation 4of the device, themagazine 24 will be retained against inadvertent removal.

The upper end 34 of the magazine 24 is tapered slightly to facilitateplacing the gummed reinforcements 36 on the magazine, the externaldiameter of the magazine being considerably less than the diameter ofthe apertures in the i f gummed reinforcements to `first dampened bymeans of the sponge iindicatedin Figure 3, andthe lower end V38 ofthemaga- Vzine 24 is Vbelled outward suiciently to prevent inadvertentremoval of the gummed reinforcements 36 therefrom.

In use, thea'pplicator is operated in the follo'wing'man'-VV nein Themagazine 24 is first removed from the housing'10jin amanner describedVhereinbefore, and a conthe 'belled end 3t3`u'ntil'the innerperiphery ofthe lowermost reinforcement is forced over the belled end 38.

When the vertical downward load is removed from the housing 10, thesmall compression spring A42 `produces axial sliding motion in the guiderod 44, returning the Ysailpin 44Vto operable position and,simultaneously, the

compression spring Y 36 movesA the magazine 24Y in aV Ydownwarddirections/ith respect to the housingl.

The magazineV24 when filledV is 'inserted into the housing llinV a manner previouslyK'described in this disclosure,`and the applicator is ready for use. l'Y Y r The paper surrounding the hole to `be reinforced is rubbermoistening Y headv 14.
